I’m trying to get rclone migrated from the old, deprecated OneDrive API to the new Graph API based on @olihey 's branch olihey/onedrive_graph. My pull request can be found here. Now the work is almost done and I would like you to help test it out. The expected advantages of this migration should be:

Less API throttling

Possibility to apply for your own Client ID / Key easily through (Docs)

More Unified OneDrive Personal / Business / Sharepoint Support

And More…

Update: The code has been merged into master, so all v1.43-beta versions that can be found on https://beta.rclone.org/ will contain this change. Thank you for your support!

Thanks @Cnly, I followed the steps in that article and the error doesn’t appear now. Although the returned list of sites for option 2 isn’t what I expected - I think it only sees document libraries within the top level site collection (orgname.sharepoint.com). It doesn’t seem to pick up on any subsites - I can only see document libraries for the top level. So to find the document library in the team site I wanted to use, I had to use the search function (option 5), which works fine.
